Vocal fatigue is known as a hyperfunctional voice disorder that can lead to other conditions, such as muscle tension dysphonia (MTD). Speech and language pathologists (SLPs) are professional voice users who may suffer from vocal fatigue due to heavy vocal demands. This study aimed at investigating the cepstral and perceptual dimensions of voice and their correlation in the SLPs with vocal fatigue. Twenty-six SLPs and senior speech therapy students (mean age = 27.11 ± 6.8 yrs), including men (n = 5) and women (n = 21), participated in this descriptive cross-sectional study. They had vocal fatigue according to the Vocal Fatigue Index (VFI). In acoustic assessment, cepstral analysis (CPP and CPPS) was performed using software. The Persian version of Consensus Auditory Perceptual Evaluation of Voice (CAPE-V) was used to evaluate the overall severity of dysphonia. The correlation between these two evaluations was also investigated using IBM SPSS Statistics software version 23. Results revealed that the mean CPPS (13.716 ± 2.084) was lower than the cutoff point. Perceptual findings indicated that the mean overall severity (10.557 ± 11.210) fell in the normal variability of voice quality (NVVQ) range. In addition, cepstral and perceptual evaluations had no significant correlation ( > 0/05). The findings showed that auditory-perceptual evaluation considered the gold standard method of voice evaluation, cannot solely identify vocal fatigue. However, cepstral measures can help provide a more objective profile of vocal function in SLPs with vocal fatigue. Therefore, both of these evaluations are recommended for voice assessment of vocal fatigue.
嗓音疲劳是一种功能亢进性嗓音障碍，可导致其他病症，如肌肉紧张性发声障碍（MTD）。言语和语言病理学家（SLP）是专业的嗓音使用者，由于嗓音使用要求高，他们可能会出现嗓音疲劳。本研究旨在调查嗓音的谐波倒谱和感知维度及其在患有嗓音疲劳的言语和语言病理学家中的相关性。26名言语和语言病理学家以及高级言语治疗专业学生（平均年龄 = 27.11 ± 6.8岁），包括男性（n = 5）和女性（n = 21），参与了这项描述性横断面研究。根据嗓音疲劳指数（VFI），他们存在嗓音疲劳。在声学评估中，使用软件进行谐波倒谱分析（CPP和CPPS）。使用波斯语版的嗓音共识听觉感知评估（CAPE-V）来评估发声障碍的总体严重程度。还使用IBM SPSS Statistics软件版本23研究了这两种评估之间的相关性。结果显示，平均CPPS（13.716 ± 2.084）低于临界值。感知结果表明，平均总体严重程度（10.557 ± 11.210）落在嗓音质量正常变异性（NVVQ）范围内。此外，谐波倒谱和感知评估没有显著相关性（> 0.05）。研究结果表明，被视为嗓音评估金标准方法的听觉感知评估不能单独识别嗓音疲劳。然而，谐波倒谱测量有助于为患有嗓音疲劳的言语和语言病理学家提供更客观的嗓音功能概况。因此，建议同时使用这两种评估方法来评估嗓音疲劳。
